Gradiški Brod
Gradiški Brod lies on the right bank of the Sava, where a crossing joins the Bosnian lowlands to the lands north of the river. The site was important in Roman times, when a naval port stood here, and the medieval town is recorded around 1330. By 1537 it was under Ottoman rule. The Ottomans built a frontier fortress known as Berbir, which Austrian forces under Laudon captured after a siege in 1789.
